A method for feeding electric power into an electric supply network using a wind park having wind power installations is provided. An expected power is determined for a predetermined feed-in period, where the expected power indicates a power value or temporal profile of power expected to be available to the park as power from wind in the predetermined feed-in period. An expected accuracy is determined and is a measure of how accurately the power reaches the expected power in the feed-in period. To determine the expected power, at least one expected wind variable representative of the expected wind speed is determined using a weather forecast, and the expected wind variable is additionally determined or verified, proceeding from the weather forecast, using a correction rule based on local weather data and/or operating data of the park. The expected power is determined on the basis of the expected wind variable.
Legal claims defining the scope of protection, as filed with the USPTO.
11. The method as claimed in claim 3, wherein comparing the forecast variable with the current wind variable includes comparing a particular adjusted expected wind speed, or the expected power with the current wind variable.
14. The method as claimed in claim 1, wherein the expected power is a sum of a plurality of rotor powers of the plurality of wind power installations, respectively.
15. The method as claimed in claim 2, wherein the forecast period is at least one hundred times as long as the particular feed-in period.
16. The method as claimed in claim 10, wherein the wind park computer has an uninterruptible power supply and, in the event of a network failure of the electric supply network, the wind park computer continues operating using the uninterruptible power supply, wherein the operating includes determining the expected power and transmitting the expected power to a network operator.
17. The method as claimed in claim 1, wherein the power value of wind power is a temporal profile of the wind power, the temporal profile including multiple power values with respect to time.
